FIRE POT ,FOB runnoI L- nummnsi Application filed January 15, 1927.Sci-talle 161,351.

This invention relates to improvements in a fuel oil burner,appertainingparticularly to the fire pot thereof thatis novel in designand embodies a baffle plate anda supporting Another objectis to providea fire pot of the character described for a fuel "oil burn'er that isopen a t-the top andlsupports abaflie plate thereabove on .acentralcoaxial stand- Whirling flame is uninterrupted. v

Another'object is the provision of a=fire pot having abafile platerotatably supported in this Way that is concavo c'onvexandlim vertablethereby enabling the adjustment ofthe height of the open ring betweenthe top of the fire pot 'Wall andthe baflle'from the latter'ofWhich-ajre'movable finger depends, near the periphery, overhanging theupper rim 'of:the pot-and intended to'break thefioodingjflameoppositejthe door of the furnace. v

Another object is to provide a fire-potfor a fuel oil burner thatisecon'omical; safe and replaced, and is thereby rendered commercially.desirable.

latedobjects that may appear, the invention resides in the construction,combination and arrangement'of parts as shall be hereinafter described,=illustrated inv the acmore fully I companying draivvlngs andpointedoutin the claims hereunto appended." The invention can be mostclearlydescribed,- and' Will be best understood when reference is had tothe accompanying drawings, forming a part of'this' disclosure and ard sothat the. continuity ofthe flooding 1n the groove\ 10; the pu-rposegofthis'sepfree from'ash, smoke, dirt or odor, giving few in Tothe accomplishment of these audit 3 wherein like characters indicatelike parts throughout' the several views. i

Thedetails of construction of this embodimentj'willnow beset forth'..;,The. fire pot proper comprises, a two piece. container; a round bowl 4with a central opening 5 Fig, 1 is aplan" VIBW oflthe' assembled i inthe base a fiangedf in'let opening? entering the bowl tangentially near,the bottom and an open'top 8, theupperjrim ofthe'circularwall9Ihayingja, central groove ll), and an annular ring lljthatj rests on.the.,wall,9,

Z A hollow, stalidardildwith" ant exterior v flange 14= ,s'paced'inf'r'om thelower endirests flange, continues through the. saidopening toterminatev fiush with the exterior of the fire p ot bowl, Air is,admitedv, to the bowl from thehollow standard 13 by air vent-s15'jthatextend radially through the Wall :ofthe standard, just. above the vflange The upper'end'of the standard is, very similarly/formed having anexterior fiange 16 spaced. from the. end to provide a supportingshoulder on the upper side for a purplose to be laterre xplained', butrounded on the under, side as at ,to deflect the. products. k ofcombustion; outwardly an'd terminally interiorly thread edjas at '18-toreceive the axiallyperforatedplug 19 that partially closes the top ofthe,standard'thu-sallowing of thefpassage of. sufficient air, admittedthrough the. lower; end ofithe pipe, toriprevent undue j overheatingo'fgthe standard and yet partially blocking theqtop end so] that some"of the current of air must find] outlet through the -,air vents-1:5; Aconcavmconvex baflle plate 20, equal in diamter to the: bowl, rests onthe'shoulder 16', havingv a' central bore21 toureceive the endof thestandard 13 above the flange This. disk-like bafile20 is loosely mountedon its supporting stand .ard being rotatable and invertable so that itsperiphery may curve upwardly from its centre or droop toward the upperrim of the built-up fire pot. To supporta" deflector 22 formed as a flator slightly arcuate depending finger with a threaded stem 23'continuingupwardly from centrally of its top, the baffle 20 has a perforation 24:,paralleling the central bore 21, near its circumference through whichthis stein is adapted to pass andfasten with a co-operating nut 25.;

It 'will of course be obvious that if desired the wall ofthe pot couldcomprise three instead of two sections, or the central standand could becast integral witli'the bowl and have its upper end partially closed orthe depending finger might be CHSt WllIh the baffle if the latter wasnot necessarilyinvertable. i

The purpose and structure of the device having been thus described indetail there now follows a brief reference'to its use and modus operandiWhen installed and placed in operation, a flame of high velocity entersthe pot through the tangential inlet 7 and whirls up the pot.Auxiliary'air enters the fire pot through the vents 15from the standard13, open through the. bottom, due to induction and a secondary currentof air passes upwards and out through the bore in the plug 19, Thewhirling flame deflected outwards by the centrifugal force of its ownaction; and by-the curved underside 17 of the standards flange 16 andthe balfle 2O flood-s out'over the'rim of the fire pot in an evenunbroken flame except for the insertion of the deflector finger 22 thatobstructs its, course. This hanging finger is adjusted to interrupt theflame opposite the door of the furnace, being spaced circumferentiallytherefrom into the path of the circling fire.

In this way no obstacle breaks the flame except to protect the dooropening so that the maximum of efliciency results from the combustionand further the force of the blast is distributed most evenly about thecircumference of the furnace thus lengthening its life of usefulness bypreventing undue concentration of the flame in limited areas of the wallthat must eventually burn through.

From the foregoing description taken in connection with the accompanyingdrawings, it will be manifest that a fire pot for a fuel oil burner isprovided which will fulfill all the necessary requirements of such adevice, but as many changes could be made I in the above description andmany apparin a limited sense.

ently widely different embodiments of my invention constructed withinthe scope of the appended claims without departing from the spirit orscope thereof, it is intended that all matters contained in the saidaccompanying specification and drawings' shall be interpreted asillustrative and not outer edge thereof.

What I claim as new and desire to secure by Letters Patent is 1; A lirepot comprising a vertical bowl having a central bore in the base thereofand a flanged oil feed opening entering tangentially through the sidewall thereof; ahol low standard exteriorly flanged at both ends; and acentrally perforated baffle plate, said standard resting in said centralbore on the shoulder a'lforded by oneflangeand supporting said centrallyperforated baflie with the other.
